Thickness is substantially greater than 1.5 millimeters.In these methods, melt is introduced into via single injection point in injection mold.Particularly, it is waiting for
Manufacture and in the case of being also configured to flat and/or plane this large-scale household appliance component over a large area,
In conventional manufacturing process, wall thickness is limited downwards.The closing forces that this is also due to injection mold are very big.Due to sizable wall
Thickness, the cooling required of melt is for a long time.
Therefore, in current manufacturing technology, especially for large-scale component, and due to economic cause, thermoforming is excellent
In injection molding.
Invention content
The purpose of the present invention is to provide one kind thus manufacturing household appliance by injection molding in an improved way
The method of component.Particularly, the present invention also aims to provide corresponding household appliance component.
The purpose is realized by method and household appliance component claimed in independent claims.
According to the present invention in the manufacturing method of the household appliance component of household appliance, the household appliance component to be complete
It is made of plastics entirely.It can be seen that the basic thought of the present invention is that household appliance component is manufactured by injection molding, wherein
During the injection molding, during at least some of stage and then at least once in a while during manufacturing process, execute specific independent
Injection molding technology combination, thus also combine the technology.Therefore, according to the present invention, in injection molding process, at it
The combination of molded (cascade molding) is molded and cascaded during at least some of stage using thin-walled injection moulding.Therefore, lead to
Cross this method, household appliance component is configured to thin wall-type, and by cascade it is molded needed for multiple injection points, can
Introduce melt.By the specific combination, realized also in a manner of particularly innovative and is advantageous：In the manufacture household appliance component phase
Between, the latching force of injection mold can remain at a fairly low.Particularly, therefore, at certain points, the melt of injection has coagulated
Gu and at other points, not yet injects or only just inject melt.This means that limited current biography can also be used herein
The injection mold that can be used in system technology.The reduction of the wall thickness of household appliance component is on the one hand so that required latching force reduces.
However, when an injection point is used only in this thin wall-type embodiment, when injecting melt, there are disadvantages, for quite big
Component, undesirable premature solidification at any and the insufficient melt to all the points supply, in such case
Under may need sizable injection pressure, this can cause the latching force of injection mold to increase in turn.In addition, in this embodiment party
In formula, it can be seen that the disadvantage is that, in cooling procedure and then in the case where plastics are shunk to a certain extent, it may
The biphasic injection only conditionally and/or in turn carried out with high pressure is needed to refill, this again leads to high latching force.
By means of the present invention, in the case that executing, thin-walled injection moulding is molding, the problem by cascade it is molded and by
Multiple injection points solve.By multiple injection points, it can prevent melt from being coagulated prematurely and very rapidly at specified point
Gu therefore can fairly evenly introduce melt, solidified in side and to the melts of all the points in injection mold to realize
Supply, fully finally to shape household appliance component to be manufactured.Therefore, by multiple injection points, be also further conducive to
Reduce the latching force associated with thin-walled manufacture needed for injection mold.Therefore, it is in two kinds of quite specific injection moldings
The novel method of the combining form of method is also allowed for using advantageous for the economic manufacture of household appliance component
And in this case only needing the injection mold and machine of smaller latching force.Since these machines and injection mold are at it
It is the important cost factor in production equipment in terms of corresponding maximum latching force, therefore the present invention may be implemented especially in this respect
Advantage.Therefore, particularly, with the aforementioned injection molding for this larger household appliance component that can only be manufactured into heavy wall component
Manufacture is compared, without using different and other injection molds of larger latching force can be subjected to, on the contrary, it is even possible that with
These traditional utensils and machine.Therefore, by means of the present invention, the initial injection of melt can be executed at injection point, and
The two of melt can be executed at the injection point cooled down before via its first melt injected in injection mold simultaneously
Secondary injection.
In this respect, the present invention is for sizable household with a large amount of planes or substantially planar flat sites
Furniture construction is particularly advantageous.Due in the case of this specific shape of household furniture construction, such as example in Domestic refrigerator
It is such in the case of the interior coating member and/or inside door of the door of tool, if the traditional injection moulding molding above described in introduction is uneconomical,
This improves through the invention.
Preferably, thin-walled injection moulding molding is executed in injection molding process, the thin-walled injection moulding is molding about wall thickness-stream
Dynamic path than characteristic parameter be more than 1: 200.Particularly advantageously, thin-walled injection moulding molding is with 1:200 to 1:300 wall thickness-stream
Dynamic path is than carrying out.This value by characteristic parameter and/or value section, it is particularly possible to realize above-mentioned advantage.Especially wanting
In the case of manufacturing the larger component with big flat site, therefore it can also realize the preferred thinness of wall, and at the same time
The enough speed of the abundant solidification and flow front of melt can be achieved.Therefore, household appliance component is accurately made in shape
It makes and is manufactured into thin wall-type, wherein even if particularly in the cooling stage shorter due to thin-walled, latching force can still be kept
It is considerably small.

With reference to advantage already mentioned above.
In an advantageous manner, the trench bottom of flute profile household appliance component is manufactured into quadrangular surface region, and described four
Second length of side, particularly height of first length of side, particularly width and/or at least 25cm of the side shape surface region at least 30cm
Degree.Therefore, the method or its advantageous embodiment party that this household appliance with relatively large surface region can be through the invention
Formula realizes that the method is related to reducing the cooling time of manufacturing process the time it takes, particularly melt, is related to injection mould
The requirement of the latching force of tool, and it is related to the clarity even if the profile of the relatively low fringe region of the injection pressure in melt
With being fully introduced into for melt.
Preferably, it according to the size of flute profile household appliance component to be manufactured, predefines molded for cascading
Injection point.
The ruler of surface region according to the size of flute profile household appliance component, particularly according to household appliance component trench bottom
It is very little, predefine the quantity for cascading molded injection point and/or position.
Particularly, the molded injection point of the cascade can according to the plane of the trench bottom of household appliance component or base
The size of the surface region of plane predefines in sheet.Since these specific geometric areas of this household appliance component are opposite
In injection point, injection pressure, melt for optionally going forward side by side slowly and distribution and the injection mould of undesirable solidification soon or too very much
It is meaningful for the optional raising of the latching force of tool, therefore it can be carried out instead in such a way that very scene is relevant
By the thinness of wall and on the other hand it answers, and on the one hand can pass through specific part note herein by advantageous embodiment
Exit point is remedied.
It is arranged in another advantageous embodiment, the size according to flute profile household appliance component to be manufactured is advance
Determine the quantity of the injection point of the longitudinal axis along Domestic refrigerator component to be manufactured and/or along household to be manufactured
The position of the injection point of the longitudinal axis of refrigerating appliance component.In this case, this is predefined particular according to household device

The size of plane or substantially planar surface region, the quantity of predetermined injection point pair.In this case, above
The advantage illustrated is also correspondingly applicable in.
In an advantageous embodiment, for utilizing in combination and and then simultaneously implementing thin-walled injection moulding molding and grade
Join it is molded come injection molding household appliance component when locking injection mold latching force be correspondingly limited to less than or equivalent
In the value of 1700 tons of weight.Particularly, which is correspondingly limited to less than or is equal to the value of 1600 tons of weight.
This is unusual advantageous embodiment, therefore, because can use wherein can actually provide these specific latching forces particularly
Injection mold as maximum latching force.Therefore, compared with the injection mold for allowing significantly larger latching force, hence it is evident that smaller,
Production cost is lower and injection mold more cost-effective in operation can be used for manufacturing process.Due in such case
Under, these be not only for special costs for injection mold of latching force it is linear, and with significantly larger degree increasing
Greatly, these disadvantages also constitute production cost pith and in turn for implements use this injection mold production
The pith of the device of method.By means of the present invention or its advantageous embodiment, can also use now has relatively low maximum lock
Determine the apparent more cost-effective injection mold of power, and still with big plane the or substantially planar surface district of manufacture
Domain above-mentioned and particularly very big household appliance component.This is impossible for pervious injection molding technology.It is thin
Wall injection molding technology makes it possible to reduce latching force with molded combination is cascaded, relatively record these are specific
, especially in the case of the household appliance component of flute profile so that traditional injection molding machine can also be used, even locked
The lower injection moulding machine of power.
By means of the present invention, these low latching forces, particularly be less than or be equal to corresponding to 1700 tons of weight value it is low
Latching force can not be only sufficiently for the initial injection process of melt, and can be additionally used in the locking of cooling period and due to cooling
The contraction of period and the biphasic injection melt that may be needed.
Particularly, as described above, the interior coating member and/or inside door of the door of Domestic refrigerator are manufactured to household appliance structure
Part.Due to their flute profile, these components are usually with sizable plane in trench bottom form or substantially planar
Surface region, thus it is particularly evident in this above problem, but by solution according to the present invention, even if in injection molding
In the range of can also carry out the advantageous manufactures of these specific household appliance components now.
The invention further relates to a kind of household appliance components according to the present invention or the manufacture of its advantageous embodiment.According to the present invention
Method, in these specific household appliance components, hence it is evident that the wall thickness of reduction, i.e. thin-walled are also possible now, and also
Quickly manufacture can be utilized to realize that the abundant complete filling of melt and sufficient second-compressed act on.For wherein to be introduced
The maximum fluidity path of melt is more than the household appliance component to be manufactured of 200mm, hence it is evident that the wall thickness less than 1.5mm is also now
It is possible.For example, if the plastics freely flowed very much are used as melt, along the longitudinal axis of household appliance component
And/or it is perpendicularly to the longitudinal axis observation so that observed in the width direction of Domestic refrigerator, the spacing between injection point can
It is larger.Therefore, the injection point quantity needed for fixed scantling is reduced.
By simultaneously and/or combination cascade it is molded, with melt fill injection mold in the thin-walled techniques not
It is carried out at the same time via all injection points, but cascade ground carries out in succession and thus.In this case, each concatenation step table
It is shown as sequence area.
In order to which melt to be introduced into injection mold to and is used in turn filling process, as described above, for each sequence area
It many different types of activation and deactivates and can specifically be directed to household appliance component to be manufactured respectively and carry out, this is unusual field
Scape is relevant.The control of sequence area for example can also be via volume injected, injection path, injection time, injection pressure or melt
The position of flow front in cavity and/or injection mold are realized.
In an advantageous embodiment, such as by measuring local mould inside pressure or topical dye wall temperature it holds
Row determines the position of the flow front in injection mold.
For this purpose, a sensor or corresponding multiple sensors can be arranged on the surface of injection mold.For example, if
More than scheduled temperature threshold, then the accurate location of the flow front in injection mold is may infer that.It, can be real by means of the present invention
Existing pure wall thickness and thin wall-type embodiment in turn is unrelated with the size of household appliance component to be produced.In addition, may also set up
At, household appliance component to be manufactured surface can completely separately structuring or at least partly individually structuring,
In can for example generate different degrees of gloss or mat surface in this case.Sensor can also be integrated in injection mould
In the wall of tool, and thus surrounded completely by the material of wall.
It is preferably set to, according to the primary or more than one frequency injection on one or more than one injection point, really
Determine the position of flow front.
It is excellent if household appliance component is manufactured by PP (polypropylene), particularly manufactured completely by PP at least partly
Choosing.The material makes the thinness using wall and multiple injection points, utilizes the mobility of the material --- PP is to flow freely,
It can particularly realize aforementioned advantages, especially have in production big plane and/or substantially planar surface region big
When type household appliance component.
In another very favorable embodiment, may also be arranged to, household appliance component is not only made of single plastics,
But it is made of at least two different plastics.This bi-component household appliance component can be for different injection points by part
Required corresponding different plastics extremely accurate produce.
By the method according to the present invention or its advantageous embodiment, many can be produced not only in shape but also in size
The different types of household appliance component of aspect.For example, small-sized thin wall-type household appliance component may be produced that with sizable flat
Face or substantially planar surface region.As a result, these household appliance components can be made into up to 30cm height,
The up to width of 15cm and less than 1mm, particularly in 0.5mm between 0.9mm, particularly the wall thickness of 0.8mm.However, also may be used
To manufacture the household appliance component of opposite bigger, the component can be configured with the height of 180cm or bigger, have 60cm
To between 90cm, particularly the width of 80cm, and particularly less than 1mm, preferably 0.5mm between 0.9mm, particularly
The wall thickness of 0.8mm.However, any median of the height and/or width and/or wall thickness all can be used as alone or in combination
Other embodiment.
As described above, by means of the present invention, the closing forces and/or lock of injection moulding machine and/or injection mold may be implemented
Determine being substantially reduced for power, the closing forces and/or latching force are in other cases required for these components.It uses
Common traditional injection moulding forming technique, stuffing pressure and/or secondary pressure act on the entire protrusion of component to be manufactured simultaneously
On surface.Therefore, for the manufacture of larger component, when being molded using traditional injection moulding, injection moulding machine needs very big closing
Power.By according to the method for the present invention, there is very big plane especially compared with remaining region with household appliance component
Or substantially planar surface region channel-shaped household appliance component in the case of, in the case of identical components size needed for
Closing force can reduce up to 80%.
Further, since the thinness of generated associated small wall thickness and wall in turn, the component area being first filled with
Domain solidifies in the filling process.This is a significant advantage.When injection mold is completely filled with melt, family to be manufactured
With the larger zone freezing of furniture construction.However, internal pressure is only still having there are still melt and in turn
It works in the region of liquid plastic.Thus internal pressure only acts upon on a part of region of entire component surface outstanding.
So that component or individual member region is caved in due to plastics thermal contraction in cooling procedure in order to prevent, is molded into traditional
In type, after completion of the filling, component to be manufactured is by secondary pressure.
In the present invention, it is molded using the thin-walled injection moulding of combination and cascades molded, after completion of the filling, this is secondary
Pressure is invalid for the member region solidified.The secondary pressure of these member regions is by during noggin piece
Stuffing pressure ensure that this is another significant advantage of the present invention.In this case, stuffing pressure is in the filling process
It is partly acted on the direction of the flow front to broaden forward and in turn first, and partly back as secondary pressure
Effect.For the flat Components Shape of household appliance component to be manufactured, the significant decrease of closing forces can only pass through combination
Thin-walled techniques and cascade molded provide.
It is produced by thin-walled, cooling time greatly shortens, and is mutually tied by flat shape and the injection point on the time staggeredly
It closes, it can be achieved that filling effect and secondary pressure effect simultaneously.Thus in plastics, there are no complete during manufacturing method and in turn
When being introduced into, the first introducing of melt can be carried out by specific injection point in specific position, and at the same time can first leading
Implement secondary pressure at the different location that the melt entered has cooled down.
